Abstract: PURPOSE: To make easy the adjustment of recording level with the illumination of display element, by changing the level of the recorded bias signal from maximum to minimum value and performing the recording and reproduction on the tape while changing again from maximum to minimum value.  
     CONSTITUTION: The 400 Hz signal is fed to the input of the line amplifier 1 and the knob of the variable resistor of the bias adjusting circuit 6 is set to the maximum position. After that, by turning the knob from the maximum to the minimum position, the recording head 7 receives the 100 KHz signal of which level is changed from the maximum to minimum value superimposed with the 400 Hz signal and the result is recorded on the tape 8. Further, this recorded signal is reproduced with the reproducing head 9 and the DC signal A corresponding to the envelope of the reproducing  signal and the peak hold signal B indicating the peak value are compared at the comparison circuit 14. The recording level is adjusted to optimized value by stopping the turning at the illumination time of the display element 18 while turning the knob of the variable resistor as mentioned above.

IPC: F17C11/00
Filed: 1983-05-18
Abstract: PURPOSE:To prevent solidification of a hydrogen occluded alloy, by a method wherein the hydrogen occluded alloy is caused to pass through a carrier gas by the use of hydrogen. CONSTITUTION:High pressure hydrogen is caused to pass through under a condition in which a hydrogen occluded alloy M is temporarily stored in a reactor 12, and simultaneously, cooling water is caused to pass through a cooling water passage 20. This causes the hydrogen occluded alloy M to make contact with hydrogen to produce a metallic hydrogenated product MH. A valve 16 is opened, and the metallic hydrogenated product MH is dropped to contain it in a receptacle 13. A valve 17 is opened, the metallic hydrogenated product MH is temporarily stored in a reactor 14 and a heating medium is caused to pass through a heating medium passage 21. In this case, the metallic hydrogenated product MH is brough into contact with the heating medium to produce the hydrogen occluded alloy M. In order to circulate the hydrogen occluded alloy M for reuse, valves 19 and 18 are opened, and the alloy is moved within a passage 22 by means of a flight conveyor to contain it in a receptable 11.

Title: Measuring device for dimension in grinding
Inventor: GOTO NOBORU
IPC: B24B49/04
Filed: 1987-04-10
Abstract: PURPOSE:To measure a dimension with high accuracy in the way of grinding by providing a cover member which is not brought in contact with the second tracing needle at least in the region of the outer circumference of the second tracing needle of the first tracing needle abutting to the upper surface of a table and the second tracing needle abutting to the upper surface of a work piece mounted on the table. CONSTITUTION:The second tracing needle 11 has a cover member 19 covering the whole region of the outer circumference thereof in such a way so as not to be in contact with the second tracing needle 11. In the way of grinding a work piece 13 with a grindstone 15 while supplying cooling water for grinding from a cooling pipe 18, the grinding is stopped once so that the first tracing needle 10 and the second tracing needle 11 are abutted to the upper surfaces of a table 12 and the work piece 13 respectively. The displacement of the second tracing needle 8 is measured as the thickness of the work piece 13. In this case, even if the temperature in the cooling wafer for grinding rises by the frictional heat of the grinding and then flows out as high temperature water, the flow is cut off by the cover member 19 so as not to be in contact with the second tracing needle 11. Therefore, the temperature of both tracing needles 10 and 11 are equal to each other so as to enable measurement with high accuracy while the rolling of the tracing needle 11 caused by the flow is eliminated.

Abstract: PURPOSE:To simplify a system and to detect precisely the combustion starting time by detecting the combustion starting time based on a microwave signal and a light signal. CONSTITUTION:A microwave 1 is transferred to a cable Fc through a circulator 2. It is converted into a wave guide mode TE in a coaxial wave guide conversion part, converted into a coaxial mode TEM in the said part, conducted to auxiliary chamber AC, and entered in a main chamber MC. If a piston is not at a resonance position, the microwave is reflected and enters a circulator 2. Then it is separated from a transmission wave, it turns into a low frequency signal owing to a detector, and it is sent to a processing part. A photodiode outputs a spark signal following ignition. The processing part III processes the low frequency signal from the detector 3 at a peak detecting part 15, processes the light signal at a processing part 16, then outputs the time difference between the central peak of the microwve signal and one tenth the peak point of the light signal at a time difference computing part 17, and displays the injection time and angle on a display unit DD1-3.
